flywheel weight

johnson pulling · Sep 9, 2008

I am new to tractor pulling with a farmall M I was wondering if adding weight to the flywheel would help with torque when the engine is about to die or would the weight needed to keep it spinning be a wash?

Smoother but not more than 1/64" farther.

Go hook it up to a big object (big tractor, etc) with a constant load (parking brake set at xx clicks). Get it on a really hard pull at 3MPH and shut the engine off. How far did you go? Now do the same thing but push the clutch in instead. See any difference?

Put a big flywheel on your pedal bike and climb a hill. How'd that work out for ya? You should see that once the engine slows to a certain point, it takes power to drive the flywheel. Flywheels were meant for high load, short duration things like brake presses.

I know what you mean, But I was thinking that since you are starting out at high rpm, the weight would have momentum and keep the rpm up longer and since the rpms are slowly dropping, the weight would not take away from the engine. It's just my theory. I have never heard anyone doing this but I was thinking of adding a flywheel from an old square baler to the belt pulley. What are your thoughts?

I'm building a lighter one for mine.

Don't sit inline with the pulley/flywheel or anybody else you care about.
Ever wonder why every other tractor pull winner doesn't have a 200lb flywheel?
Do the math and see for yourself how much energy you are saving.
You will go farther spinning out rather than stalling out. So why does storing the last little erg or energy matter?
